Mrs Herbert Fischer aka Mary Louisa Jackson by Julia Margaret Cameron, 1864
Mary Louisa Jackson (December 30, 1841 – August 24, 1916) was born in Calcutta. She was the daughter of John Jackson, MD and Maria Jackson.
She was the wife of Herbert William Fisher. She was the mother of Florence Henrietta Fisher; Herbert Albert Laurens Fisher, FRS; Arthur Alexander Fisher; Adeline Maria Vaughan Williams; Emmeline Mary Morris; Edmund Montagu Princep Fisher; Hervey George Stanhope Fisher; Admiral Sir William Wordsworth Fisher, GCB; Charles Dennis Fisher RNVR; Cordelia Curle and Edwin Fisher. Hard to believe that she had eleven children!
She was the sister of Adeline Maria Jackson; George Corrie Jackson and Julia Prinsep Stephen (aka Julia Jackson).
Two of her children – Florence Fischer and Herbert Albert Laurens Fischer – can be seen on this photo here, with their aunt Julia Duckworth (nee Jackson) in 1872.
On the above photo Mary was 23 years old, and in January that year she had given birth to her first child, daughter Florence. On this photo she might actually already be pregnant with her next child, Herbert, who was born in spring the following year. In any case, she looks pretty exhausted on this picture.
